It looks like it was a linker problem. I rolled back to GCC 4.0.2, and
it got past the initial kernel panic.

It's now panicking on a PCI transaction, but at least it gets to the
kernel's main code.

I'm avoiding the 2.6 kernel because it lacks Xilinx IP driver support
(at least on a production level).
